Apparatus, method and system for generating a foveated image

Abstract

The present disclosure relates to an apparatus, method and system for generating a foveated image. According to the present disclosure, an apparatus for generating a foveated image, the apparatus may comprise a communicator configured to transmit and receive a signal and a processor configured to control the communicator, wherein the processor distinguishes objects comprised in a hologram, which is generated for a front field of view by using input light, selects an object to be targeted among the distinguished objects, and generates a foveated image by using depth information of the targeted object.

What is claimed is: 
     
         1 . An apparatus for generating a foveated image, the apparatus comprising:
 a communicator configured to transmit and receive a signal; and   a processor configured to control the communicator,   wherein the processor distinguishes objects comprised in a hologram, which is generated for a front field of view by using input light, selects an object to be targeted among the distinguished objects, and generates a foveated image by using depth information of the targeted object.   
     
     
         2 . The apparatus of  claim 1 ,
 wherein the selected object exists in a central region of the generated hologram.   
     
     
         3 . The apparatus of  claim 1 ,
 wherein the depth information of the selected object is measured through laser-based light detection and ranging (LiDAR) and a time-of-flight (ToF) camera.   
     
     
         4 . The apparatus of  claim 3 ,
 wherein a field of view of the LiDAR is adjusted to aim a region comprising the selected object.   
     
     
         5 . The apparatus of  claim 1 ,
 wherein the hologram is based on complex optical information that is obtained by a single-camera optical system.   
     
     
         6 . The apparatus of  claim 1 ,
 wherein the objects comprised in the generated hologram are distinguished based on a depth map and color information of the hologram.   
     
     
         7 . The apparatus of  claim 1 ,
 wherein the hologram is iteratively generated, and   wherein the selected object is an object that changes in at least one of depth and size in the iteratively generated hologram.   
     
     
         8 . The apparatus of  claim 1 ,
 wherein the selected object is determined as an object with risk of collision.   
     
     
         9 . The apparatus of  claim 1 ,
 wherein the input light is used to generate the hologram and measure the depth information by being separated into two optical paths through a wavefront separator.   
     
     
         10 . A method for generating a foveated image, the method comprising:
 distinguishing objects comprised in a hologram for a front field of view, which is generated by using input light,   measuring, by selecting an object to be targeted among the distinguished objects, depth information of the selected object; and   generating a foveated image based on the measured depth information and the generated hologram.   
     
     
         11 . The method of  claim 10 ,
 wherein the selected object exists in a central region of the generated hologram.   
     
     
         12 . The method of  claim 10 ,
 wherein the depth information of the selected object is measured through laser-based light detection and ranging (LiDAR) and a time-of-flight (ToF) camera.   
     
     
         13 . The method of  claim 12 ,
 wherein a field of view of the LiDAR is adjusted to aim a region comprising the selected object.   
     
     
         14 . The method of  claim 10 ,
 wherein the hologram is based on complex optical information that is obtained by a single-camera optical system.   
     
     
         15 . The method of  claim 10 ,
 wherein the objects comprised in the generated hologram are distinguished based on color information and depth distribution of the hologram.   
     
     
         16 . The method of  claim 10 ,
 wherein the hologram is iteratively generated, and   wherein the selected object is an object that changes in at least one of depth and size in the iteratively generated hologram.   
     
     
         17 . The method of  claim 10 ,
 wherein the selected object is determined as an object with risk of collision.   
     
     
         18 . The method of  claim 10 ,
